JOHN GLADING COUNCIL, OF NORTHAMPTON, MASSACHUSETTS, ASSIGNOR TO MGCAL- LUM BIOSIERY 00., OF NORTHAMPTON, MASSACHUSETTS, A. CORPORATION OF 'MAS SACHUSETTS RUN-STOP COURSE FOR KNITTED FABRICS.

Application filed May 1a, was. Serial m. masts.

My invention relates to the knitting art and has as an object a novel form of stitch adapted to be knitted at any point in the fabric where it is desired to prevent runs from passing, and it is thus particularly applicable to hosiery, where it is desirable to knit a course of such stitches a suitable distance below the welt for the purpose of preventing runs starting above such course, or in the garter welt, from passing below it into the leg of the stocking.

My invention also extends to the method of producing such a stitch, or course, or courses of stitches, as well as to certain mechanism which I. have devised which is especially suitable for the carrying out of the said method and producing the said stitch.

In the accompanying drawings, in which like reference characters designate corresponding parts in all views,,and in which is illustrated a preferred embodiment of my invention Figure 1 is a diagram showing my new stitch;

Fig. 2 is a front view of a novel form of welt bar applicable in carrying out my in vention;

Fig. 3 is an end view of the bar shown in Fig. 2;

Fig. 4 is a detail showing how alternate sinker wale loops are engaged by the hooks of the bar; and

Fig. 5 is a. detail showing how the loops are spread by means of said special welt bar.

Referring to the drawings, and especially Figure 1, I have shown a small section of knitted fabric including five courses 41-45 inclusive, composed of needle wales 51--5(i inclusive, and sinker wales 6l-66 inclusive Courses 41 and 42 are composed of ordinary loops making up the body of the fabric,

- Course 43 is the runstop course, and it is comprised of undisturbed needle wale loops, into which sinker wale loops 1 of alternate wales 62, 64, 66, etc. are spread and knitted, v

the sinker wale loops 2 of intermediate wales 61, 63, 65, etc., being left undisturbed.

Courses 44 and 45 are composed of ordinary loops, and continue the body of the fabric The method of procedure at the po nt where it is desired to prevent runs which may be started in the preceding portion of the fabric from passing beyond into that subsequently knitted is as follows: After a course 12 of plain knitting, which may if desired be a loose course, a loose course 41-3 is drawn in the usual manner; alternate sinker wale loops 2 of this course 43 are no run which starts in the fabric knitted before the runstop course will pass into the fabric knitted subsequently.

It is thus apparent that my new runstop course may be formed simply by spreading alternate sinker wale loops 1 of a single courseover the adjacent needles 3 at each side, without disturbing any of the needle wale loops, or the intermediate sinker wale loops.

In order tofacilitate the spreading of the sinker wale loops 1 over the needles 3 as described I have devised the novel form of welt bar 10 shown in Figs. 2 and 3 which may be used in carrying out the invention on a straight knitting machine. The bar or clamping member 11 may be of the usual type, and have the hooks 12, 13 fastened in place in the usual manner. The number and spacing of the hooks of course corresponds with that of the needles of the knitting machine with which it is intended to be used, in the usual manner. This welt bar differs however in that, while alternate hooks 12 are of the ordinary type, the intermediate hooks 13 have been cut off short as shown, and are in fact not hooks at all, but are joined at their ends each to the hook 12 at one side, as by solder 14. I

In making my run stop by the use of the special welt bar 11 as shown iii-Figures 2 and 3, the preferred procedure is as follows:

A. loose course 43 is drawn, and the weltthe hook 12 at the right hand end of the bar between the first and second needles. The machine is then operated to cause the sinker wale loops to be engaged .by the hooks 12, which extend into alternate sinker spaces, so asto engage the loops 1 of the wales 62, 64, 66, etc. The welt-bar 11 is then drawn forward, tightening the loops 1 upon thehooks12, as indicatedin Figure 4. The bar 11 is then tilted to raise the hooks 12, and the loops 1 are caused to slide down and spread over the half-hooks 13 as shown in Figure 5.

The barll is then applied to the needles 3 in exactly the same manner as when the welt is turned, to place the loops 1 over the needles. The needles in the meanwhile continue to hold the needle wale loops. The half-hook 13 at the right is applied to engage the right hand needle; the hook 12 joined thereto is applied to the second needle, and so on. 'Thus the loop 1 of sinker wale 62, being spread on hooks 12, 13, slides off the said hooks which are placed by the bar on the needles of needle wales 51 and 52respectively, and the loop 1 is thus delivered in spread condition over both these needles, as indicated in Fig. 1, the needle walesupon the needles being undisturbed.

The special welt bar 11 may then be removed in the same manner as when a welt has been turned, and regular knitting is proceeded with, the first course 44 being a loose course if desired.

Having now described my invention, a novel run stop stitch or course, the method of making the same, and a novel form of welt bar for use in connection therewith,

I claim and desire to secure by Letters Patent:

1. In a knitted fabric, a course having alternate sinker wale loops spread and'knitted into the adjacent needle wales of the same course at each side.

2. In a knitted fabric, a course comprising a full course of normal needle wale loops, and combined therewith alternate sinker wale loops spread and knitted into 4. In a knitted fabric, a loose course having alternate sinker wale loops spread and knitted into the adjacent needle wales of the same course at each side.

5. The method of forming a run-stop which consists in drawing a loose course, spreading alternate sinker wale loops thereof over the adjacent needles at each side, while the needles continue to hold the needle wale loops of said course, and drawing another course.

6. In the formation of a run-stop, the

step of the process which consists in spread-.

ing, sinker wale loops of a course over needles at both sides while the needles retain the needle wale loops of said course.

7. In the formation of a run-stop, the step of the process which consists in spreading sinker wale loops of a course over the adjacent needles at both sides while theneedles retain the needle wale loops of said course.

8. In the formation of a run stop, the step of the process which consists in spreading alternate sinker wale loops of a course over the adjacent needles at each side while the needles retain the needle wale loops of said course. i Y

9. A welt bar comprising alternate hooks and half hooks spaced apart the'same distance as the needles of the knitting machine, the half hooks being secured at their ends each to a full hook at one side.

10. A welt bar comprising hooks spaced to take alternate sinker wale loops, and means to spread such loops wide enough to go over two needles.

In testimony whereof I have signed my name to this s ecification.
